QuickTime 10.4 (833.6) weird movies/videos runtime numbers?

As you can see from the photo above, the elapsed and remaining times are weird.

This has been going on for weeks now, and I sadly do not recall if anything in particular started it...

I just noticed it...one day...and it won't go away.

Happens with any video I play in QT, no matter the size, length or format.

It just won't show the correct times, and I often must switch to VLC to see how long a movie is overall, for example.

Anyone have an idea how to fix this? As said it won't go away no matter what! 😕
